Abstract

The Study of Potato Variety Assessment Resistence for Phytophthora infestans Disease in District Karo, North Sumatra. Potate is a main potential commodity in  North Sumatra where the poduction was marketed to fulfill local and regional needs. This research was done in Cinta Rakyat Village, Simpang Empat Subdistrict, Karo Regency, North Sumatra which was located at 1,250 m above the sea level.  In this research four vatrieties were used; Granola, Atlantik, Kikondo, Margahayu and 0981-1085 Strains which were arranged by random Block Design and each treatment repeated 5 times. The distance between these plants was 30 cm x 80 cm, the plot measurement was 3m x 4 m (50 plants). The distance between each treatment was 50 cm, the distance between each repetition was 100 cm. To protect this plant from diseases several materials were used; 20 t/ha manure, 200 kg/ha urea, 400 kg/ha SP- 36, 200 kg/ha ZA, 150 kg/ha KCl.  Where as pest control was adjusted with the local condition. The research results after 70 days of plantation showed that the lowest intensity of Phytophthora  infestans disease was found  in Strains 0981-1085 (64.45%) treatment, where as the highest intensity was found in Granola variety (79.75%). The highest production was found in Strains 0981-1085 (31.89 t/ha) treatment, whereas Granola variety only reach 12,95 t/ha.  The R/C value was Granola (1), Margahayu (1.6), Atlantik (1.8), Kikondo (2.2) and 0981-1085 (2.5).Tanaman kentang merupakan salah satu komoditas unggulan dan menjadi sentra di Sumatera Utara, produknya dipasarkan untuk memenuhi kebutuhan lokal dan regional.  Kajian ini dilaksanakan di Desa Cinta Rakyat, Kabupaten Karo, Sumatera Utara, ketinggian 1250 m dpl.  Varietas kentang yang digunakan, yaitu: varietas Granola, Atlantik, Kikondo Margahayu dan Galur 0981-1085.  Menggunakan Rancangan Acak Kelompok, setiap perlakuan diulang 5 kali.  Jarak tanam kentang 30 cm x 80 cm, jarak antar perlakuan 50 cm.  Pupuk yang digunakan: pupuk kandang ayam 20 t/ha, Urea 200 kg/ha, SP-36 400 kg /ha, ZA 200 kg/ha, KCl 150 kg /ha.  Pengendalian hama disesuaikan dengan kebutuhan.  Hasil kajian menunjukkan bahwa tanaman pada umur 70 hari setelah tanam (hst), intensitas serangan Phytophthora infestans terendah terdapat pada perlakuan 0981-1085 (64,45%) sedangkan intensitas serangan tertinggi terdapat pada perlakuan Varietas Granola (79,53%).  Produksi tertinggi terdapat pada perlakuan Galur 0981-1085 (31,89 t/ha), sedang Varietas Granola hanya mencapai 12,95 t/ha.  Hasil perhitungan antara penerimaan dan pengeluaran (R/C) memberikan nilai secara berturut-turut Granola (1), Margahayu (1,6), Atlantik (1,8), Kikondo (2,2) dan Galur 0981-1085 (2,5).  Dengan demikian, tanaman kentang Galur 0981-1085 dan Kikondo layak untuk ditanam.

Abstract

The Package Technology of Red Onion in Haranggaol, North Sumatera. The cultivation of red onion around Toba Lake has not been developed well due to pest and disease problems, improper cultivation practices adopted by farmers as characterized by the planting local varieties. A study was conducted in Haranggaol, North Sumatra in an effort to introduce suitable technology needed for increasing production. Two high yield varieties `Tiron and Thilipina were planted using two recommended technology packages which were then compared to local practices. Research results indicated that Tiron produced the highest number of tiller i.e. 17.30/cluster, while Philipina yielded the highest production (20.51 t/ha) with larger size of bulb (141 bulb/kg). In comparison, Tiron produced 7.88 t/ha with higher number of bulb at 237 bulb/kg while local variety produced 7.43 t/ha with 221 bulb/kg. The highest reduction of bulb weight after 60 days stored was Philipina reached 20.40%, Tiron 19.20% and local variety 18.80%. The control of Spodoptera exiqua by using feromon­exi showed that 1,059 heads of imago could be trapped. If one pair of imago can produced 500-600 eggs, it can be estimated that this treatment could kill 635,400 larvas of Spodopthera exigua. Results also indicated that the package technology 2 with Philipina showed R/C at 2.8, followed by package technology 1 with Tiron variety at 1.7 and local practice at 1.2 Key words: Red onion, technology package, varietyPertanaman bawang merah di sekitar kawasan Danau Toba tidak berkembang bahkan cenderung menurun akibat serangan hama dan penyakit, budidaya yang masih tradisional dan belum digunakannya varietas unggul. Berkaitan dengan hal tersebut, telah dilakukan suatu pengkajian perbaikan budidaya dan varietas unggul bawang merah di Desa Haranggaol, Kecamatan Haranggaol Horisan, Kabupaten Simalungun, Sumatera Utara. Teknologi yang diterapkan adalah bawang merah varietas Tiron dan Philipina yang ditanam dengan dua paket teknologi anjuran dibandingkan dengan teknologi petani. Hasil kajian menunjukkan bahwa jumlah anakan tertinggi diperoleh pada varietas Tiron (17,30/ rumpun). Produksi yang tertinggi didapat pada varietas Philipina yaitu 20,51 t/ha dan umbi lebih besar (141 umbi/kg); Tiron 7,88 t/ha dengan jumlah umbi 237/kg sedangkan varietas lokal hanya mencapai 7,43 t/ha dengan jumlah umbi 221/kg. Penyusutan setelah 60 hari dalam penyimpanan tertinggi terdapat pada varietas Philipina mencapai 20,40%, Tiron 19,20% dan Samosir 18,80%. Pengendalian hama spodoptera exigua dengan pemasangan Feromon-exi dapat ditangkap imago jantan sebanyak 1.059 ekor. Jika sepasang imago mampu bertelur 500 — 600 butir maka diperkirakan dapat membunuh larva keturunannya mencapai 635.400 ekor larva Spodoptera exigua. Hasil perhitungan menggunakan R/C secara berturut-turut Teknologi-1 (Bawang Tiron) sebesar 1,7; Teknologi-2 (bawang Philipina) sekitar 2,8 dan Teknologi Petani (Bawang Samosir/Lokal) sebesar 1,2.

Abstract

Shallots are one of the horticultural commodities that have fluctuating prices. Market integration occurs horizontally but not vertically due to poor information systems at the producer and consumer levels. This study aimed to estimate the area of shallot land quickly using the rapid classification of croplands method. The research was conducted in Merek District, Karo Regency, North Sumatra. Primary data obtained from survey activities were processed using the Google Earth Engine platform. Classification and regression trees (CART) and random forest (RF) algorithms were used to classify land cover as onion and non-onion classes. The shallot land area based on this method was 74.4 hectares, with an area accuracy of 95% (RF) and 24% (CART) and a location accuracy of 92% (CART and RF). The rapid classification of croplands method can estimate land area quickly. It helps stakeholders who need information on shallot production projections and can be developed to improve the vertical market integration information system (market integration between producers and consumers). Some areas for improvement of this method are limited access and resolution, inability to describe up to the level of garden bunds, and the condition of the area covered by clouds, which will affect the accuracy of the results. Keywords: shallots, production estimation, google earth engine, remote sensing
